For several reasons, Switzerland and Austria are of interest to researchers analysing the factors that influence levels of childlessness. The countries are similar in terms of population size, standard of living, and socio-economic setting. The Alpine regions have traditionally had rather high levels of childlessness, with a significant proportion of women and men remaining single (Viazzo 1989). The current population of Switzerland is about 8.2 million, of whom 65 % are German-speaking, 23 % are French-speaking, and 8 % are Italian-speaking. As each canton has its own official religion and language(s), there are French-and German-speaking Catholic, Protestant, and secular cantons. In the age range 20-39 a third of the population has foreign citizenship. These immigrants come not only from the neighbouring countries of Germany, France, and Italy, but also from ex-Yugoslavia, Portugal, and Spain. Austria has a slightly larger population, at 8.6 million, and the official language is German, with 89 % of the population speaking German as their mother tongue. The proportion of foreigners in the country is less than half that of Switzerland, with immigrants from Germany and the countries of ex-Yugoslavia and Turkey being the most numerous. Around 20 % of women in Switzerland who have reached the end of their reproductive years have no children, while the corresponding figure in Austria is a little lower, at around 18 %.
